There's a syntax error on line 30, but I have no clue what the error is. Help?

Toodles.py

import os
import keyword
import sys


class Toodles:
	
	def walkAndList(directory):
		for dirname, dirnames, filenames in os.walk(directory):

			# print path to all filenames.
			for filename in filenames:
				workingFilename = os.path.join(dirname, filename)
				if(isSourceFile(filename)):
					listOccurrencesOfToDoInFile(filename)
		
			# Advanced usage:
			# editing the 'dirnames' list will stop os.walk() from recursing into there.
			if '.git' in dirnames:
				# don't go into any .git directories.
				dirnames.remove('.git')
				
			for dirs in dirnames:
				self.walkAndList(os.path.join(dirname, dirs)


	# 	Find occurences of "todo" and "fixme" in a file
	#	If we find such an occurence, print the filename, 
	#	the line number, and the line itself.

		input = open(aFileName)
